It could well be down to the tyres, your clothing or shoes.Have you recently bought new footwear? some soles insulate better from static than others so don't discharge static when you touch the ground.Artificial fibre clothing i.e. fleece jackets are made from respun plastic bottles and hold static like little devils.Low carbon tyres don't ground out very well and hold static more.

Strangely, I get terrible static shocks from supermarket trollies if i push them over laminated flooring (like the dreaded electrical and clothing departments in Tesco's).I have to hold the metal parts rather than the handle to discharge static as it builds or else i get a nasty bolt every time.

Whats wrong with static shocks? I build it up every time I get off my chair at work, can get some proper good cracks when touching metal things (or colleagues)! I also get it every time I leave my car and touch the door to close it. The blue bolt looks good at night!

Hi fellas, Diesel Pig, new shoes- now that I never thought of and it might be the cause for me starting to suffer some interesting shocks, combined with some frosty mornings this week.
certainly wakes you up in a morning!!
